Capybaras are semi-aquatic rodents whose zoo welfare depends fundamentally on regular access to water for swimming, thermoregulation, and social behaviour.
Capybara welfare in zoo settings requires water access as a non-negotiable element of habitat design. As semi-aquatic animals, capybaras are strongly motivated to enter water and use it for multiple essential functions. Without adequate pool access they develop dry skin, foot problems, and inability to perform normal social and comfort behaviours. Their gregarious social nature means that solitary or paired housing also represents a significant welfare compromise.
